The space between scenery changes is far too great.
Players get bored before making any substantial progress.
The Solution
Make campaign 30 levels instead of 90, split the other levels out and have them as bonus levels.
This allows for more engagement with the story
Helps reduce the scope of the game to a more managable level
Leaderboards
The Problem
The hover is difficult to work with.
Leaderboard types cant be changed easily by the user.
Limited space for entries
The Solution
Rebuild the level select screen.
Make a dedicated section for leaderboards
(Possibly) allow swapping between 'friends' 'top 10' and 'around you' modes.
Timeframe
Time managment: Time working on game vs. Time learning more
The issue right now is I've dedicated all of my time to RM which means I'm not spending anytime learning basic things from the course I've been doing, a lot of which I would have been able to use in the creation of RM and saved me a lot of time.
I am going to spend 2 days a week educating myself, and 3 days working on RM. This will allow me to maintain the current progress rate and maybe even develop faster in the long run. However it does mean for about a week, 2 at most, I won't be releasing any updates.
Your feedback and ideas are immensely helpful to me, so if you want to provide it you can reach me on discord, I am MrVastayan
